  Motivation Counting manually isboring and monotonous!
• 4.
  Objectives  To implementa counter that can count up to 10,000.  To automate current system of counting.
• 5.
  Introduction  This projectfocuses on building an effective counter using IR as a sensing element and and will be capable of counting from 0 to 9999.  This circuit is designed using CMOS lCs, with advantages like: o Very low power consumption. o Wide supply voltage range o Good noise immunity o High package density o High fan-out capability

  Future scope  Inreal time, by using advanced sensors the distance between receiver and transmitter can be increased and can be useful to count heavy objects.  Using different sensors and technologies, we not only can increment the count of objects but can also decrement of no of objects going out.
